Title: Separation of gas with membrane
Inventor: MARUO KATSUHIKO
IPC: B01D53/22
Filed: 1988-05-18
Abstract: PURPOSE:To improve permeation velocity and separation performance by arranging the electrodes to both sides of a membrane, ionizing gas by dielectric breakdown or forming either a nonuniform electric field or a uniform electric field and allowing electric force to act on the gas. CONSTITUTION:In the separation with a membrane wherein a gas separation membrane 1 is utilized, (A) the molecules of the aimed gas are ionized by impressing high voltage between the electrodes arranged to both sides of the membrane, (B) the porous membrane 1 is utilized and the aimed gas is subjected to capillary condensation in the pores of the membrane and also a nonuniform electric field is formed by the electrodes 23, 24 arranged to both sides of the membrane, or (C) a uniform electric field is formed by the electrodes arranged to both sides of the membrane. Since the gas aimed for separation can be allowed to act with electric force by these constitutions, permeation and separation performance of the separation membrane can be improved. Furthermore the composition of the permeated gas can be set at prescribed value only by controlling voltage and current between the electrodes without adjusting the flow rate and the operation pressure of the gas.

Abstract: PURPOSE:To smoothly execute a robot operation by deriving an interpolation point to which the robot moves, by using a track data, and also, decelerating it by decreasing successively an interval of the interpolation point, and accelerating it by increasing said interval. CONSTITUTION:In a track data storage means 10, a track data at the time of a usual operation is stored in a time series. When a receiving means 60 receives a temporary stop command, a track data in an interpolation point determined by a deceleration instructing means 70 is derived by an interpolation point operating means 40, and instructed to a robot. When the receiving means 60 receives a restart command, a track data in an interpolation point determined by an acceleration instructing means 80 is derived by the interpolation point calculating means 40, and instructed to the robot. Since the interpolation point is derived, based on the track data as a reference, it does not occur that the robot deviates from the track due to accelerating/decelerating operations, and the robot operates smoothly even at the time of acceleration and deceleration, since an interval of the interpolation point is varied gradually against the interval of the track data at the time of the usual operation.
